111 Instruments and controlsAir distributionThe air distribution control is used to direct the flow of air to the
defroster, panel and floor vents.
The control also permits settings in between the three main settings
defroster, panel and floor:
 defroster and floor
 panel and floor
 defroster, panel and floor (11 o’clock position)
To counter cold drafts from the front side windows when the control
has been set to defroster or floor, a small flow of air issues from
the outer vents on the fascia.
As the winter comfort setting, we recommend that the distribution
knob be turned to .
Recommended settings in severe coldOn starting with a cold engine, set the fan speed to 2 or 3 and select
maximum heat and defroster to heat the cabin and demist the wind-
shield as quickly as possible.
When the engine is warmer and the temperature gauge starts to
rise, fan setting 4 may be chosen. Once the windshield is clear, the
air distribution control should be turned to .
If the rear seat passengers desire more warmth to the feet, turn the
distribution knob one step clockwise.
How quickly the engine warms up will depend on how the car is
driven. It will take longer for the engine to warm up if the car is driven
in a high gear at low engine speeds, such as in town, than if it is
driven at high engine speeds on a highway, for example.
Do not use fan speed 5. This is primarily intended for rapid cooling
during the summer. Using it in cold weather will delay the engine
warm-up time and providing heat to the passenger compartment.

Air ventsThe air vents swivel universally, so that air
can be directed as desired. In winter, for
instance, the outer vents can be directed
onto the door windows for enhanced
demisting.
The amount of air can be individually con-
trolled by the regulator on each vent. If you
wish to reduce the airflow, start by half-
shutting the vent in question.The air conditioning is combined with the
conventional climate control system and
is switched on by pressing the but-
ton, provided that the fan control is in
position 1-5.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled; and finally, if required,
it is heated.
If the engine coolant gets too hot, the A/C
compressor will be turned off.
Convertible: When the soft top or all the
windows are open in a hot, humid climate, it
is recommended to switch off the air condi-
tioning to save fuel. Also, if the air condition-
ing is on, condensation may form on cold
surfaces such as the floor air ducts.
Condensation waterWhen the A/C compressor is on, the incom-
ing air is dehumidified. The resulting con-
densation water is drained away through an
outlet under the car.
It is therefore perfectly normal for water to
be seen dripping from this outlet when the
car is parked. The warmer the ambient air
and the higher the humidity, the more con-
densation will form.
When the button is pressed, the reg-
ular air intake will be closed. In this mode,
the air inside the cabin is recirculated.
Use recirculation when you wish for rapid
cooling at very high outside temperatures.
Switch the air conditioning (A/C) on first.
If necessary, recirculation can be switched
on manually to avoid unpleasant air from
entering the car.
Only use recirculation for a short period
of time at temperatures lower than 50°F
(+10°C), such as to avoid unpleasant air.
Mist or ice may otherwise form on the
windows.

114 Instruments and controlsThis button is located under the fan speed
control.
Always switch off the heating as soon as the
rear window is free from ice and mist. It will
be turned off automatically after 12 minutes.
Refrain from placing sharp objects on the
parcel shelf, to avoid damaging the heating
element.
Convertible: The rear window heating is
not turned on if the soft top is folded down.The seat cushions and backrests of the front
seats are heated.
The heating is thermostatically controlled
and set at approx. 104°F (40°C).
Switch off the seat heating once the seat is
warm.

115 Instruments and controls
Automatic climate-
control system (ACC)Fresh air for the cabin is drawn in through an
inlet at the bottom edge of the windshield. It
passes through an effective filter before
reaching the climate control system and
delivery into the cabin. The air is evacuated
via openings in the parcel shelf. It is then led
through outlets on either side of the car
behind the rear bumper.
The Automatic Climate-Control system
(ACC) automatically maintains the desired
cabin temperature, regardless of the
weather outside.
The system will achieve the desired temper-
ature in the quickest possible way.
Note that heating or cooling is not
speeded up by setting the temperature
higher or lower than the final tempera-
ture you desire.
To optimize the performance of the air con-
ditioning system, all windows and the sun-
roof should be shut. The air vents in the
fascia must be open.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled; and finally, if required,
it is heated.To reduce potential misting on the insides of
the windows, the glass should be cleaned
with a quality glass cleaner. How often this
will need to be done depends on how clean
the air is - if there are smokers in the car, the
windows will need to be cleaned more
frequently.

116 Instruments and controlsTemperature controlThe cabin is divided into two temperature
zones:
1 Driver’s zone.
2 Passenger zone.
The temperature in the rear seat will be a
mixture of the two zones.
If you choose the single zone setting, the
entire cabin is treated as one zone. If you
choose the dual zone setting, settings can
be made separately for the driver’s zone
and passenger zone.
Select between single and dual zone set-
tings under Profiler (see page 124).
The cabin temperature can be set to
between 58–82°F (15–27°C). In addition, HI
(maximum heating and high fan speed) and
LO (maximum cooling and maximum fan
speed) can be selected. HI and LO can only
be selected for the passenger zone if the
driver has selected the same setting.The displayed temperature is not the actual
air temperature but corresponds to the
comfort level normally experienced at that
temperature after allowance has been
made for the airflow, relative humidity, solar
radiation, and so on, currently prevailing
inside the car.
 The most usual temperature setting is
between 66–74°F (19–23°C), depending
on personal preference and what clothing
is worn.
 Change the temperature setting in 2°F
(1°C) steps.
 Make sure the air vents are open when
cooling the cabin in warm weather.
Settings when HI is selected:
 Maximum heat
 Air distribution to windshield and floor
 High fan speed (6 bars on the fan display).
Settings when LO is selected:

The system uses four sensors:
 Outside air temperature sensor
 Cabin air temperature sensor
 Sun sensor
 Blended air temperature sensors (located
in the heater unit and the outer panel vent
duct).
The sun sensor is located centrally on the
top of the fascia.
Note:
If the sun sensor is covered, the ACC
system will not be able to regulate the cabin
climate as intended, especially in strong
sunshine.Condensation waterWhen the A/C compressor is on, the incom-
ing air is dehumidified. The resulting con-
densation water is drained away through an
outlet under the car.
It is therefore perfectly normal for water to
be seen dripping from this outlet when the
car is parked. The warmer the ambient air
and the higher the humidity, the more con-
densation will form.
